26 THE GENUS FUMARIA IN BRITAIN 



recurved. Sepals 4-5 nivi. long and 2|-3 7mn. broad, ovate, peltate, 

 occasionally subentire but generally irregularly dentate towards 

 the base, acute or shortly acuminate, whitish or rosy in colour, 

 with greenish median line, broader than the corolla-tube, and 

 contiguous below. Corolla 10-12 mm. long, rose-pink in colour, 

 with the tip of the inner petals and the ivings of the upper one 

 blackish-red. Upper petal broad and dorsally compressed, acute, 

 apiculate or rarely obtuse, with a spathulate dilation of the wings 

 which, exceeding the keel, often extends almost to the apex, and 

 is obvious in the bud stage though obscured when, in flower, the 

 wings reflex upwards and cover the keel ; spur shorter than the 

 sepals. Loiver petal loitli erect and narrow margins, often deflexed 

 and free. Fruits of moderate size, about 2| mm. long, and 2 mm. 

 broad, obovate and rounded-obtuse in profile, a little compressed 

 laterally but obscurely keeled, and narrowed below to an obscure 

 fleshy neck not broader than the tip of the pedicel ; smooth or 

 finely rugulose when dry, with small but distinct apical pits. 



Forma rubens. 



F. Borcei var. verna Pugsleyin Journ.Bot.xl. p; 177,nonClavaud. 



Habitu typi, sed foliis parvis rubicundis, sepalis rubris, corolla 

 magna speciosa saltem 12 mm. longa profunde rosea petali su- 

 perioris alis latis atropurpureis. 



In habit resembling the type, but with small, vinous-tinted 

 foliage. Flowers large and handsome, fully 1^ mm. long, and deep 

 rose-coloured, with rosy-red sepals, and broad, blackish-red wings 

 to the upper petal. 



Forma elongata. 



Ut in typo robusta sed laxa internodis longis diffusa ; folia 

 plus minusve glauca ; racemi pauciflori (saepissime sub-10 flori). 



As robust as the type, but very lax and diffuse, with long 

 internodes and more or less glaucous foliage. Eacemes rather 

 few (usually sub-10) flowered. 



^. AMBiGUA Pugsley in Journ. Bot. xl. p. 178. 



In habit similar to the type, but with narrower, lanceolate 

 leaf-segments, rather smaller flowers, and narrower, more acu- 

 minate sepals. Fruit nearly 2| mm. long, and almost as broad, 

 more compressed laterally than in other forms of F. Borcei, hardly 

 narrowed below, and consequently nearly square rather than 

 obovate in profile, with a fleshy neck equalling or overlapping the 

 tip of the pedicel ; when dry, finely rugulose with rather faint 

 apical pits.
